Please note, This instructor-led course has specific dates and times:
This course is held online over 3 days on the following schedule (All times in Eastern Time Zone):
Day 1 & 2: 10:00 am to 6:30 pm Eastern (Will include the usual breaks and lunch)
Day 3: 10:00 am to 2:30 pm Eastern (Will include the usual breaks)

After participating in the course, you will be able to:

  • Apply basic principles of solar cell operation and comply with the electrical authority and system operator
  • Perform AC and DC system losses, fault analysis at combiner boxes and assess solar farm site
  • Complete design layout and orientation, financial evaluations and operation of string and utility-scale inverters
  • Transform to AC and connection medium voltage (MV) and high voltage (HV) distribution system and addition of battery energy storage system (BESS)
  • MV AC collector system design
  • Understand safe design (DC and AC arc flash analysis, labelling and interlocking)
  • Project scheduling and commercial aspects

In Canada, the growing and constantly evolving solar PV systems are unfamiliar to many engineers involved in power generation. The course deals with solar site assessment, installation consideration, financial evaluation of design, DC and AC losses, utility-scale and string inverters, project scheduling, MV and HV distribution, PV system commissioning and local utility and authority technical requirements.

This course focuses on ground-mounted, grid-connected, medium and large utility-scale solar farms connected to medium and high-voltage circuits. Participants will also learn about overall solar farm configuration, including DC and AC design and conceptual design of MV substation and AC collector circuits.
